make a die to produce them. And dies for making counterfeit money can be produced without any trouble. These are the evils, on the other hand the cheapness with which endless facsimiles may be made of wood and other engravings will materially lessen the price at which books with good pictures can be sold, and there is no saying where this thing is to end; dies for embossing plate can be multiplied, and every thing that has a raised surface can be copied exactly.

We saw in the lecture room numerous living animalculæ in water, exhibited through Cary's Oxyhydrogen Microscope, upon a screen containing four hundred and twenty-five square feet, and to see the hundreds of monsters of horrid shapes in a drop of water magnified so as to appear several feet long, and to see a flea made to look as large almost as an Elephant, and the myriads of live eels in a bit of sour paste no bigger than a pin's head filled us with wonder and awe of that Being, who has created the most minute living thing with all the air vessels and all the functions of life similar to the larger objects of his creation; and when we remembered to have heard it said, that there were men who say there is no God, we could only wish that such men, if any such there be, could be brought here to see these things, and then surely if they were not devoid of all reason they would say these things cannot be the effect of chance; there must have

been, and now is a great, a good God who created all things for some wise and good purpose, and if we cannot penetrate all his designs, if there are some things for which we cannot account, let us bow with awe before our Creator, and acknowledge that all his productions are good, and let all human beings upon the face of the earth praise the Lord their God.

There is a very complete laboratory under the Hall, where Mr. Maughan, Chemist of the Institution, has a chemical glass, and where ores, minerals, earths, &c. are tested and their component parts made known.

In a room under ground there was a beautiful picture of Canton by a Chinese Artist, twentyfive feet long, magnified very much by powerful glasses. And through them we looked upon two paintings on glass from pictures by the celebrated Mr. Martin, "Joshua commanding the sun to stand still," and "the destruction of Nineveh," and they were most beautiful. Opposite to these several drawings taken by the Daguerreotype were exhibited through powerful magnifying glasses, and we have to express our thanks to the gentleman who exhibited them, and who we understood to say that he had taken several of the views himself, for his kindness in changing the pictures several times whilst we were there, in order that we as inhabitants of another land might see as much as possible. We saw a view near Windsor, some

views taken from the front of the Institution and several views of places in and near Paris. We should not forget to mention that the temperature of the whole building is kept uniform and of a pleasing warmth by Bramah's hot water apparatus. We looked into an apartment where there was a remarkable model of a portion of the Isle of Wight, modelled according to a scale, by Captain Boscawen Ibbotson, and where every elevation or declivity, every hill, every thing upon it for nine miles is shewn with mathematical precision; we were told it was the work of many years, and we should think that an individual, who was capable of producing so finished, so laborious a piece of art as this, could have been much more beneficially employed, for after all it is good for nothing, you peep through the glasses and see that it is there, and regret that so much valuable time should have been consumed in so valueless a production.

We were much pleased to see a great many models of machines for cultivating the earth, agricultural instruments upon improved plans; of ploughs, harrows, rakes, threshing machines and bone crushers, and drills for sowing seeds instead of throwing them with the hand: a beautiful model of a shop front in Regent Street very much pleased us. We were also pleased with the twenty-three articles illustrating the English manufacture of glass at Mr. Apsley Pellatt's Glass

Works, Bankside, London. Here were articles of all sorts of colours, beautifully cut; in particular the Queen's portrait, and a decanter with equestrian figures from the Elgin Marbles in the British Museum: there were also beautiful specimens of the manufacture of English China-ware, being part of services executed for the royal castle at Windsor. We also saw a beautiful specimen of ivory turning, being a bust of the Queen, and several small busts of the Queen, Prince Albert, and Duke of Wellington, in marble, and a beautiful specimen of cloth manufactured from glass. We here saw a pneumatic telegraph (Crosley's) which, by means of air in a tube, will convey signals many miles; and Dr. Arnott's hydrostatic bed, upon which sick persons can move readily, and are not liable, if confined a length of time by illness, to become sore from lying in bed. We saw also a specimen of cloth four thousand years old, taken from a mummy; a very ingenious weighing machine (of Marriott's): you sit down in a chair, and a hand, like that of a clock, points out your weight. We observed a very curious Egyptian astronomical clock, made by Mr. T. Richards of Droitwich, and it is an illustration of the Egyptian system of astronomy; representing the eastern hemisphere of the earth as a fixed body, the tides in progressive motion round the earth, the moon, surrounded by stars, performing her diurnal motion round the earth, to

a second of time; exhibiting her phases, indicating her age, her position in the heavens, her proximity to the sun, her time of rising, setting, &c. The sun, as a body, is represented making his apparent diurnal revolution; his situation in the heavens, together with the minute he rises and sets each day; the relative duration of day and night; the sun's meridian altitude; the ebbing and flowing of the tide in the Thames is seen in a view of London, and the time of high water is pointed out; the day and the name of the month are exhibited throughout the year, with the number of days in each month. This clock has been in action two years, and fully realizes the expectations of the inventor; the mechanism and combinations being quite free from perplexity, its motions are not liable to derangement, and it requires no other attention than a common time-piece.

There are two most amusing machines, called Phantasmascopes, one on each side the gallery on the brass rails. A large circular plate, called a disc, is perpetually revolving; and when you look through the apertures in the one, the optical deception is so arranged that, from the quick revolution of the disc, all the figures appear to be rapidly playing on the fiddle, and in the other playing at leap frog," that is jumping over each other's backs.
